The LackRack

The first implementation: Red LackRack with Ethernet switch and table lamp

First occurrence on eth0:2010 Winterlan, the LackRack is the ultimate, low-cost, high shininess solution for your modular datacenter-in-the-living-room. Featuring the LACK (side table) from Ikea, the LackRack is an easy-to-implement, exact-fit datacenter building block.
It's a little known fact that we have seen Google engineers tinker with Lack tables since way back in 2009.

The LackRack will certainly make its appearance again this summer at eth0:2010 Summer.

Summary

When temporarily not in use, multiple LackRacks can be stacked in a space-efficient way without disassembly, unlike competing 19" server racks.

The LackRack was first seen on eth0:2010 Winterlan in the no-shoe Lounge area. Its low-cost and perfect fit are great for mounting up to 8 U of 19" hardware, such as switches (see below), or perhaps other 19" gear. It's very easy to assemble, and thanks to the design, they are stable enough to hold (for example) 19" switches and you can put your bottle of Club-Mate on top! Multi-shiny LackRack can also be painted to your specific preferences and the airflow is unprecedented!

Howto

You can find a howto on buying a LackRack on this page. This includes the proof that a 19" switch can indeed be placed in the LackRack in its natural habitat!

Assembly

Illustration of the LackRack's modularity

For assembly in terms of a programming language, this is not the page you need.

However, in order to assemble the LackRack, there are a few prerequisites or tools that are needed:

1 (or more) LACK side table from Ikea

Screwdriver (whether muscle-driven or motor-driven, with preference of the latter)

Wood screws (they should fit in the rack mounts on your appliance, and not exceed 1" in length)

Spare time

That's all! First, follow the assembly instructions in the Ikea manual in order to assemble the LACK.
After that, the installation of your 19" hardware can begin. When assembling a larger number of LACKs, this link describes a useful tool for fitting the legs to the tabletop.

The LackRack is a stackable modular product. Additional elements can be stacked on top easily. Brackets to secure the top element to the bottom one are not included but available from your local non-computer hardware store.

If you put several LackRacks side by side, the higher levels can be staggered to form a pyramid. This feature is not present in any other of the commercially available rack products.

Installation

Due to their light weight design, Lackracks will grow to any required size without compromise

Installing hardware in your LackRack is easy!

Optional but recommended - Put the table on its side (which one is your decision) or upside down

Mount the hardware between the left and right leg

If you mount the first item, it is recommended to install it against the table top for good fit. This happens automatically if you have the LackRack upside down, except in zero gravity environments.

Screw all the screws that fit in the rack mount in the left and right leg (for stability).

With deep units, a Z-shaped bracket may be advisable to secure the rear of the unit against the underside of the tabletop.

Alternative configuration

Mounting the equipment to the rear of the front legs is recommended if you plan to fit switches with fiber uplinks; the created tabletop overhang shields the fiber connections from minor mishap

FAQ

Q: Does the LackRack provide redundant power supply?

A: Only if you add it yourself

Q: Can I put my (coffee) mug on top and don't have to worry about it if I spill liquid on the LackRack?

A: You can spill coffee on the LackRack, since it can be cleaned quite easily. However, if you have appliances in the LackRack, there is a chance that these appliances cannot handle the coffee (or any other liquid). You should take precautions in order to protect your appliances

Special Editions

Enterprise Edition

Norco RPC-3216 mounted in a LackRack Enterprise Edition.Additional brackets used to raise the shelf and support the 45kg+ weight.

Ikea LACK coffee table: almost twice as deep, and comes with a shelf. Its size allows both short ends to be used as rack space simultaneously. It's interesting to note that Ikea photographed it from the side; an uncommon artistic approach to 19" server rack photography.
It provides for 8 U of hardware: 4 on either side of the shelf.

Following ICT tradition, the Enterprise Edition is more than three times as expensive, while providing less stability than two of the regular products combined.

Levenstein distance of "Lack" and "Rack" is 1. Can this still be a coincidence?
